You'll go blind eventually 
That only happens when you play with your joystick too much!

coombz,plz dont direct nonplayers to post in help in training,there's enough wrong imformation being spewed about in there now.
FYI the reduction in speed doesnt increase turn rate,it decreases the turn radius, also the "dive" flaps on the P38L arent dive flaps they are dive recovery flaps and only change the airflow around the tail. The flaps dont produce very much drag like you would find with real dive flaps.
YMMV.
